The branch main has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=49b6254b3e09ee741f456617111ecb18803459fb commit 49b6254b3e09ee741f456617111ecb18803459fb Author: Colin Percival <cperciva@FreeBSD.org> AuthorDate: 2026-02-22 04:09:00 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2026-03-28 05:54:49 +0000 vmm: Move defines from x86.c to x86/bhyve.h The values CPUID_BHYVE_FEATURES and CPUID_BHYVE_FEAT_EXT_DEST_ID are useful for guests, not just hosts; so they belong in a header file in sys/x86/include rather than simply in the .c file implementing the bhyve host side. The original addition of these defines took place without adding a copyright statement, but since I'm moving them into a new file I've added the original author's standard copyright (Amazon).
